Ingredient review
Sequoia Stem Extract
INCI: SEQUOIA SEMPERVIRENS STEM EXTRACT
A gentle, antioxidant-rich botanical extract that may help protect skin from environmental stress, though human studies are limited.
In plain English
Sequoia stem extract comes from the stems of the giant sequoia tree, one of the oldest living trees on Earth. In skincare, it's used as an antioxidant—meaning it helps neutralize unstable molecules called free radicals that can damage skin cells. It also has some skin-soothing properties. Because it's a natural extract, its exact composition can vary, and most evidence for its benefits comes from lab studies rather than large human trials.

What it is
A natural extract derived from the stems of Sequoia sempervirens (coast redwood), rich in polyphenols, flavonoids, and other antioxidant compounds.
How it works
The polyphenols in sequoia stem extract help neutralize free radicals generated by UV exposure and pollution, potentially reducing oxidative stress on the skin. It may also have mild anti-inflammatory effects, helping to calm irritated skin.
